tryder the boxer used to be very leash reactive. His owner Linda struggled with him lunging at other dogs for no apparent reason. He got into an unfortunate fight with a dog at the dog part which only exacerbated the problem. I worked with positive reinforcement methods, re-teaching his obedience in a positive way and with better motivation. Within about 5 weeks he showed enough improvements like going to public parks where many dogs and people gathered, going into a Home Depot, and remaining entirley attentive to his owner.
